I.
Course Description
Beginning statistical theory and practice are introduced through topics of data collection, sampling techniques, organization
and presentation of data, measurement of central tendency, probability concepts, statistical estimation, hypothesis testing,
correlation analysis, linear regression and analysis of variance. There will also be some time devoted to symmetry and
examples of mathematical precision and beauty in God's Creation.

IV. Course Methodology and Materials
About the first 15 minutes of each class period will be used to answer student questions, and to give surprise review quizzes.
The remainder of the hour will be used for lecture, discussion, demonstration and class work. Homework exercises will be
assigned for each chapter. Homework will not be formally evaluated often, but it is absolutely essential that students keep
current and do all homework exercises. In this way they will understand where their difficulties lie and be able to ask
questions in class or during office hours, or over the telephone, and thus build on their knowledge in ensuing class periods.
WARNING: Learning mathematics is a cumulative experience. New knowledge depends on understanding previous
material. For this course it is imperative that you do you work every day and seek extra help in office hours when
necessary. If you are unprepared even once, you may never catch up.
Required Text: The Basic Practice of Statistics by David S. Moore, 5th edition,

Attendance Policy
A. Attendance is expected at every meeting of the class.
B. Students should notify the instructor of excuses for class absence, before the class for that day by phone or email.
C. Whether present or absent the student shall be accountable for all classroom learning experience, all announcements
made in class, and all assignments.
D. If the student has not excused their absence any quizzes given, tests given, or assignments collected that day will
be counted as a 0% (zero) grade. These grades cannot be made up. Please Note: Students who are in choir, band,
athletics, or any other group representing WLC are required to excuse their absences in advance, themselves. Excuses
may be sent by email to [email protected], or text message to: 262-510-2046, or voice at : 262-510-2046.
E. In the event a student is absent from a test for a valid reason, and has excused their absence, the student is responsible for
making prompt arrangements with the instructor for a make-up test.
F.
VIII.
Attending another section of the same class is acceptable. Please check with the professor in advance. Changing sections
to take a quiz or test at a different time than you are scheduled is only allowed with advance permission.
